STAPLE-SET.

Patented May 23, 1911.

` Application filed May 22, 1909. Serial No. 497,593.

To all whom 'it may concern: r

Be it known that I,v AUBREY O. HIGH- sMrrH, a citizen lof the UnitedStates, residing at Dallas, in the county of Dallas and 5 State ofTexas, have invented certain new and useful Improvements in Staple-Sets,of which the following is a specification.

My invention relates to new and useful improvementsin staple` sets,foruse more particularly in building and repairing wire fences.

The object of my invention is to provide a device of the characterdescribed, which will be strong, durable, simple and eflicient, andcomparatively easy to produce, and one in which the various parts willnot be likely to get out of working order.

With these and Various other objects in view, my invention has relationto certain novel features of construction and operation, an example ofwhich is described in vthe following specification and illustrated inthe accompanying drawing, wherein:

Figure 1 is a longitudinal, sectional elevation of the device. Fig. 2 isa side elevation thereof. Fig. 3 is an end elevation, and Fig. 4 is adetail of a rivet, designed to prevent longitudinal motion of the rodpassing through the center of the tool.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in all the figures, the numeral 1denotes the head member of the tool, which member is adapted to be usedasa claw-hammer, being provided with a hammer portion 2, and the usualbifurcated claw 3. Into the head member 1 is threaded the metal tube 4,which forms a portion of the handle member. A smaller tube 5 is threadedat one extremity into the tube 4 and has an apertured cap 6 threadedupon the other extremity. Between the tube 4 and the cap 6 is clampedthe handle proper 7, which ts upon the tube 5, and is constructedpreferably of wood. An aperture 8 of approximately ellipticalcross-section eX- tends centrally into the head member 1, in alinementwith the handle member, and the cylindrical, central aperture of thelatter continues into the head member connecting with said ellipticalaperture.

Operating in the longitudinal central aperture of the tool is a plunger9, which is provided with a plunger head 10, tting in the aperture 8 ofthe head member, and having the same elliptical shape. This plunger headprevents rotation of the plunger rod and also prevents the rod beingwithdrawn through the handle, as it is seated upon the shoulders 11,formed by the juncture of the elliptical aperture 8, with the circularaper- `ture extending 'into the handle member.

Upon the other extremity of the plunger 9 is provided a head 12, whichprevents the withdrawal of the plunger throughy the head member. Thehead 12 is upset upon the plunger .after the latter has been insertedthrough the central aperture of the tool. A groove 13 extendingtransversely of the plunger is adapted to receive the rivet 14, securedin the tube 4. This rivet is provided with a screw-head whereby it maybe turned, and has a fiat surface 15 cut into the side. When the surface15 is turned toward the plunger 9, the latter is free to slidelongitudinally, but when the round surface of the rivet is so turned asto enter the groove 13, the plunger is held rigidly. A gage 16,preferably of steel, is adjustably mounted upon the head member 1, by apin 17, having a head 18 integral therewith at one extremity and amilled nut 19 threaded upon the other, Vby which nut the gage may beclamped in any desired position. A plurality of apertures 20 areprovided to the gage, spaced one inch apart, through any one of whichthe pin 17 may be passed. A scale of inches marks the distance of eachof these apertures from the outer extremity of the gage 16.

When the tool is used as a staple driver,

the staple is dropped into the aperture 8 of the head member, with thepoints outward. The wire which the staple is to hold is caught in recess26 in the head member, and the latter applied to the post where thestaple is to be driven. A mallet or hammer is now used upon the head 12of the plunger 9, driving the staple without possibility of its bendingor danger of striking the fingers. The elliptical aperture 8, whichreceives the staples is set in the head with its axes at an angle withthe center lines of the head to avoid driving the two staple points intothe same line of the grain, thereby avoiding risk of splitting the woodinto which the staple is driven an embedding the staple more firmly.

In withdrawing staples, the head member is placed upon the staple insuch a manner that the exposed portion of the staple enters the aperture8. Using the gage 16 as a lever and holding the head firmly down uponthe staple, the tool is now twisted several times, thereby loosening thestaple,

Still keeping a torsional strain upon the staple, the tool is now swungto one side, using the claw 3 as a fulcrum and extracting the staplefrom the post. The hammer portion of the head memberl is set back fromthe apertured face thereof, forming the shoulder 27. VThis permits saidface to be projected into smaller spaces in driving` or extractingstaples. y I

` What I claim is:

An implement for use in building and repairing wire fences, consistingof a hammer head having a transverse aperture therethroughhaving theapproximate form of an Gopies of this patent may be obtained for ellipsewith its axes at an angle with the hammer edges, a handle memberprovided with a Vtubular central aperture communicating with thetransverse aperture of the head, a plunger slidably mounted in thehollow handle, having its end projecting therefrom,

and means by which said plungerv may be`4 made rigid with the handlesubstantially as described. y

In testimony whereof I have signed my name to thisspecifcation in thepresence of two subscribing witnesses.
